ladder is leaned against a building. the bottom of the ladder is 11
feet from the building. the top of the ladder is 19 feet above the
ground.
a. what is the slope of the ladder?
slope = rise / run = height / base = 19 feet / 11 feet = 19 /11
b. what does the slope of the ladder mean in the real world?
The slope is the inclination of the ladder. The higher the slope the more leaned is the ladder.
c. if the ladder were set closer to the building, would it be harder or
easier to climb? explain in terms of the slope of the ladder.
if the ladder were closer to the building the base would be lower and the heigth would be higher, so the slope would be higher, which means that the ladder would be steeper, therefore harder to climb.

33 photos in a 4x to 7x ratio
4x + 7x = 33
11x = 33
x = 3
33 photos can be put in a 4(3) to 7(3) ratio
which is a 12 to 21 ratio
so 12 photos on one side, and 21 on the other side to get the ratio of 4 to 7
Note:
<span>a(b) = ab = a x b = a times b</span>
We set up a proportion: ?/22.50= 35/100
Cross multiply:
100*?= 22.50*35
⇒ ?= 22.50*35/100= 7.88

Answer:
This has 2 solutions
Step-by-step explanation:
This question has 2 solutions because the answers can be x=1 and x=-4 because 5-8=-3 and you can get 5 with a absolute value and 5-8=-3
